Working hours average

[Aviral Sharma]

Hi
I have a database of a person's working hours where I have his three months
extra or less working hours. I want an average of all the three months.

Can someone help me with the formula for this average. Here the average
formula is not giving the correct value.

Month 1 Month 2 Month 3 Average
-08:31:00 -24:50:00 21:01:00 ?

I suggest you work with "decimal days" instead of time.
